Code:
g_custom_text[32] = register_cvar("sa_custom_text","")

This is wrong. register_cvar always returns an integer and it's a cvar pointer to a cvar, which you can use to get_pcvar.

Along with that

Code:
get_pcvar_string(g_custom_text[32], g_custom_text, 32)

This is wrong. First of all the first argument is a cvar pointer you got from registering a cvar, in your case this throws an error.

Also length should be sizeof - 1 ( In your case 31, or just use charsmax(buffer) )

This native returns a number of cells written to a buffer, so keep that in mind.

Can I fix it by using create_cvar instead?
